Adding a provider to the Search Internet option

Adding a provider to the Search Internet option

I have recently signed up to Findmypast.co.uk and have been trying to add the provider to the option to Search for current person on the internet.Following the Legacy's Help options it would seem that the URL returned for searching Findmypast differs from the example given there i.e. http://www.findmypast.co.uk/XdbSearchCountServlet.Any help would be appreciated.Andy Claxton
